A childhood belief about condoms

When I was around eight my discovered I had som pornomags I had found in a container. She told me that the people in the magazines were doing bad things, and that it was dirty. Then naturally she threw them away. At this point I had learned what a condom was, and was horrified when I discovered that my dad had pack in his nightstand drawer. I couldn't figure out why they would do something that bad, and I thought somehow they must be slowly be going insane. It was the only explanation I could come up with. I was terrified because of this, because I wouldn't know what to do if they actually went nuts after a while. Finally I mustered up the courage to confront them about it, and my dad explained to me how grown ups have something called sexual urges, and that if they didn't have sex now and then they would go insane. I hadn't mentioned the insanity part of my assumption when asking about, so I was even more puzzled by this. Actually I think he meant to say that it would become frustrating after a while, but of course I didn't understand until much later. After that I thought adults would end up in the nut house if they didn't have intercourse on a regular basis, and I still couldn't fogure out why I was told it was bad when it was magazines, but not elsewhere.
